This exploratory study investigates methods for enhancing Flickr tags as image metadata through the creation of context. Community generated tags from a sample of images in the Library of Congress’s (LOC) Flickr photostream were harvested and compared to metadata from related Wikipedia articles. In addition, a content analysis of comments in the LOC photostream was conducted. This informs an exploration of methods of combining user-generated tags with other resources to create richer, contextual metadata for images. In addition, the LOC and Wikipedia subject terms were compared to subject headings from the Thesaurus for Graphic Materials (TGM) to determine whether socially created metadata can be used to enhance a current knowledge organization tool by suggesting new concepts, terms, and relationships.
